/etc/default/sysklogd?

In Debian 4, it seems that the sysklogd initscript does not
check any /etc/default (like sysconfig in redhat) file,
and in fact sets SYSLOGD=""
SO I gather I need to edit the initscript if I want to change
syslogd's commandline params, or is there some other local
mechanism that allows me to make config changes w/o touching the
file (which may get overwritten on a future upgrade)?
